One of a series of units on business issues designed for secondary school students, this packet focuses on the farmers' cooperative corporation, a particular type of business organization created to increase farmers' control of the production and marketing of their goods. Two separate sections consist of a teacher's guide and student materials. The teacher's guide contains an overview of objectives and activities, an activity to pre-assess students' knowledge of the business concepts basic to this unit, five daily lesson plans, teacher background information, student handouts, and recommendations for using business people as classroom resources. The student materials section contains eight activities that treat the organization, functions, and economic role of farmers' cooperatives. Students examine three case histories: a Kansas wheat farmer in the 1890's, the development of the Sunkist cooperative, and new farmworker cooperatives in Salinas, California. Readings outline the history of the farm problem and compare the cooperative to other types of businesses. Two problem-solving exercises involve students with the issues of overproduction and monopoly. A vocabulary worksheet reviewing terms and ideas presented in the unit concludes the activities. (LP)
